I am guessing it might be related to permissions, does it work without sudo?

firefox without sudo did not work,the same as sudo .Other program work without sudo but can not run with sudo

@qyw233 what is the output of systemctl status user.slice? Here's output of Firefox on Ubuntu, Firefox was installed as a snap:

@qyw233 By default sudo does not preserve user env vars set by wsl. In order to preserve env while running the command with sudo you need to add -E flag:

-E, --preserve-env
Indicates to the security policy that the user wishes to preserve their existing environment variables. The security policy may return an error if the user does not have permission to preserve the environment.

try running apps with:

$ sudo -E <comm>

@elsaco I install firefox by atp

[qyw233]

@tusharsnn Oh！I can use sudo -E geany to open geany.But firefox cannot open with or without sudo.

john@ThinkPad-E480:~$ firefox Unable to init server: Could not connect: Connection refused Error: cannot open display: :0 john@ThinkPad-E480:~$ sudo -E firefox Running Firefox as root in a regular user's session is not supported. ($HOME is /home/john which is owned by john.)

firefox cannot use sudo

Currently we are aware of systemd and WSLg is not working along on Ubuntu 20.04. You can try Ubuntu 22.04 or 18.04, or Debian as workaround, we will look into the root cause with 20.04, thanks!

systemd and WSLg does not work on my Ubuntu 22.04 installation .. Could be related to #844

[hideyukn88]

Hi all, WSL 0.70.0 is just released and it addresses various issues with systemd, including the problem like this, please update by wsl --update, and if it still doesn't address, please let us know by reopening this issue, thanks!
